Yes pretty much
So add a brazil address and use a br gift card whilst signed into vpn and that's all? Thanks
You can buy Brazil Xbox credits from Eneba. I brought AC Origin Gold edition and Odyssey Ultimate edition,this way. https://www.eneba.com/xbox-xbox-live-gift-card-50-brl-xbox-live-key-brazil
Done so this evening without the card
I think you need to entire a credit card with a brazil address to be able to redeem brazil codes.
